Broker & Buyer Comments

This "exceptionally well-run" 51-story tower offers "dramatic" UN views from its prime Turtle Bay perch. The "sophisticated" building impresses with a "striking" brick-and-glass facade, "grand" drive-in porte-cochere and "spectacular" multi-level garden plaza complete with waterfall. While interiors may be "dated," "world-class" amenities abound including a 5000 SF fitness center, pool and 24/7 staff. The "prestigious" location near Grand Central, Tudor City and Beekman Place puts Manhattan at your doorstep.
